TRAVELER STOP FOR SPINNING RINGS.

Application filed June 1Q. 1922. Serial No. 567,331.

To all whom it may concern:

Be it known that I, LITFALLAH G. SABBAG, a citizen of the United States,residing at Boston, in the county of Suffolk, State of 5 Massachusetts,have invented a certain new.

and useful Improvement in Traveler Stops for Spinning Rings, of whichthe following is a specification, reference being had therein to theaccompanying drawings.

0 The invention is applicable in connection with ring spinning frames. I

It has relation more particularly to the rings and travelers whichareemployed in.

showing a further embodiment of the inring spinning frames.

It consists in a spinning ring having in connection therewith astop-device by means of which the traveler mounted upon the race of suchring will be arrested at a predetermined point in the circuit of thering, whenthe yarn being spun breaks orslackens, or

when the operation of the spinning frame is stopped. i I

One special object in view' is to enable the spinning frame attendant tofind the traveler at once for the purpose otpiecing up a yarn which hasbroken between the front drawing-rolls. and the spinning spindle.

Another special object is to render it possible to stop the traveler insuch a position as to-facilitate the operation of doiiing.

The invention is capable of being embodied in a variety of ways. theseare illustrated in the drawings, in which latter, i

Fig. 1 shows in eleva'tiona portion of the ring-rail of a ring-spinningframe, a ringholder and ring with traveler mounted on the race of thering, and a spinning bobbin, and shows also one illustrative embodimentof the invention. 4

Fig. 2 shows in elevation, detached, the ring-holder and ring of Fig. l,with the traveler removed.

Fig. 3 shows in plan the parts which are shown in Fig. 2, with atraveler added thereto and engaged with the traveler-stop.

Fig. 4: is a view looking from the right.

hand side in Fig. 3, with the ring partly broken away adjacent thetraveler-stop, and with a traveler mounted on the ring and in engagementwith the traveler-stop.

Fig. 5 is an elevation of a portion of a ring-rail, a ring-holder, ring,and traveler,

showing a second illustrative embodiment 5 of the invention, with thetraveler held clear Certain of of the traveler-stop by the yarn which isengaged with the traveler.

Fig. .6 is a view looking from the rightvention, without a traveler. I

F igi 10 is a view of the parts of Fig. 9 in vertical section on line10, 10, of Fig. 9, with a traveler mounted on the ring and in therelation to the traveler-stop which it assumes during normal spinning.

Fig. 11 is a top view of portions of the ring-holderand ringof Figs. 9and 10, with the traveler omitted.

Fig. 12 is an elevation similar to Fig;

9, showing another embodiment of the in vention. 1

Fig. 131 is a viewin vertical section on line 18, 13, of Fig. 12.

Fig. 14.- is a plan view. partly broken away, of the embodiment of theinvention that is shown in Figs. 12 and'13.

Fig. 15 is a view similar to Fig. l3,showing a further modification. ofmy invention. The portions of ring-rails which are showninFigs. 1, 5, 6,7, and 8 of the drawings, are marked 1. A spinning-ring holder 2 andspinning-ring 3 are shown in each of the views of the drawings. The saidholder and ring may be as heretofore, or .as preferred, except asindicated hereinafter in eX plainingthe invention. Fig. 1 shows aspinning-bobbin i extending up through the spinning-ring 3 of such view,with a partial load 5 of spun yarn wound upon the lower portion of suchbobbin. The traveler is marked 6 in each view in which it is shown.

The invention utilizes the principle that the upward pull of the yarn 3Figs. 1, 5, 6 and 10, in process of being spun in a ringspinning frame,will hold the traveler up as in such views, with its hooked extremitiesin contact with the under sides of the top flanges of the ring, so longas the yarn continues unbroken and is maintained taut bobbin on whichthe yarn is wound as fast as it is spun; and that when the yarn breaks,

or when the yarn is slackened in case of.

with a spinning-ring a traveler-stop which.

is so located, relative to the path in which the traveler moves aroundthe ring under normal conditions, that so longas the yarn continuesunbroken and remains taut the stituted by a shoulder 8 at the top of thering produced by. the removal of some of the material of the ring-top.Preferably the portion of the ring-top immediately in advance of thesaid shoulder is so formed as to slope or incline downward, as at 9,toward the shoulder 8. With this construction of the top of the ringitself, the yarn y will normally hold the traveler up, as in Fig. 1, sothat it will travel around the ring-race with its bent body-portionelevated at a height which will avoid engagement of the traveler withthe shoulder. In case of breakage of the yarn, however, or ofslackeningof the yarn asin case of stop page or the ring-frame, thetraveler will drop until its bent body-portion rests upon the ring-top,and the traveler will slide around upon the ring-top under the momentumit has acquired, until it encounters the shoulder 8, as indicated inFigs. 3 and 4: andis stopped thereby. The sloping top surface at 9 justin advance of the shoulder 8 facilitates the movement of the traveleraround to the stop and tends to cause the travelerto remain alongsidethe stop.

Figs. 9, 10 and 11 illustrate a travelerstop 81 that is constituted by aslight upward projection upon the ring-top. Fig.

10 shows how the traveler 6 clears such projection so long as the yarn yremains unbroken and taut. The manner in which the moving traveler willengage with the projection in case of yarn-breakage or stopping of thering-frame will be evident.

Figs. 5, 6, 7 and 8 illustrate a travelen stop 82 which is constitutedby a tongue or spur struck up from the sheet-metal ringholder 2, andextends up alongside the body of ring 3 to a point just below the normalbody of the ring 2, at the exterior of said body, at a pointsuiiiciently below the traveler-race, by screwing said shank into ascrew-threaded hole in the said body.

Fig. 15 shows a traveler-stop, 84:, on the same order as that of Figs.12, 13 and 14, but applied at the interior of the ring.

Still further modifications are permissible.

What is claimedas the invention is, 1. A spinning-ring having inconnection therewith a traveler-stop permitting the.

traveler to move undisturbed around the ring during normal spinning butengaging therewith to stop the traveler in a predetermined position incase of yarn-breakageor stoppage of the spinning-framer 2. Aspinningring having in connection therewith a fiXed'traveler-stoplocated clear of the path in which the traveler moves normally duringthe spinning operation but adapting it to arrest the traveler in apredetermined position in case the traveler is freed by yarn-breakage orthe yarn is slackened, as by stopping of the spinning-frame. Intestimony whereof I afiix my signature in presence of two witnesses.
